the brain edema is one of remarkable injuries after traumatic brain injuries (tbi). the common treatments for limiting edema are included mannitol, barbiturates, corticosteroids, hyperventilation and central nervous system derange. the most of these treatments for edema is problematic. for example, mannitol can be effective for the short period of time (24 hours) after brain injuries but is not...

traumatic brain injury (tbi) is one of the leading causes of death in men under the age of 35 that mostly occurs due to the road accidents. current clinical treatments have not enough repair and prevention of secondary damage caused by cytotoxicity. progesterone, as a primary sex hormone, acts as neuroprotection in tbi and stroke. progesterone increases anti-oxidants and decreases inflammation ...

Background: Progesterone is essential for establishing and maintaining a pregnancy. However, premature atresia of the corpus luteum (CL) or sub-optimal progesterone secretion after ovulation may result in decreased ability to establish maintain The current limitations serum hormone testing fail give complete picture production across luteal phase required

There is controversy about the beneficial effects of topical progesterone creams used by postmenopausal women. A major concern is that serum progesterone levels achieved with progesterone creams are too low to have a secretory effect on the endometrium. However, antiproliferative effects on the endometrium have been demonstrated with progesterone creams when circulating levels of progesterone a...

Acute application of progesterone attenuates cardiac contraction, although the underlying mechanisms are unclear. We investigated whether progesterone modified contraction in isolated ventricular myocytes and identified the Ca2+ handling mechanisms involved in female C57BL/6 mice (6-9 mo; sodium pentobarbital anesthesia). Cells were field-stimulated (4 Hz; 37°C) and exposed to progesterone (0.0...
